But with that approach, you should do them all -- the current solution will barf on the first digit past the one that the number is a multiple of. (That is, if you feed it 30, it will barf due to var_v being nil; if you feed it 150, it'll barf due to num_x being nil, etc.) Another one would be to just output the needed digits immediately, rather than stashing the number of them and outputting them later. -Dave -- Dave Aronson, President, Dave Aronson Software Engineering and Training Ruby on Rails Freelancing (Northern Virginia, Washington DC, or Remote) DaveAronson.com, Codosaur.us, Dare2XL.com, & RecruitingRants.com (NEW!)
